Four More Questions You Might Get in a Data Science Interview Part 2 of a miniseries crafted by somebody with experience as a data science interviewer Hello again friends! Welcome back with the continuation of our series on interview questions you might get in a data science interview. In case you missed the first post, you can check it out at this link. I’m going to keep this introduction short and sweet since I give a better, more thorough explanation in the original post. Let me provide a very quick recap on how these posts are structured. Across all four questions, you will see two subsections: Also one last reminder: the questions I’ve crafted across both posts run the full gamut of data science skills. Depending on the specific role you apply for, you may or may not encounter questions similar to these, but I still wanted to provide a broad range of types of questions to cover that “full stack” of data science skills. Alrighty, I promised a short and sweet introduction, so let’s jump into the questions! 1. Across various cloud platforms (including AWS SageMaker), it is possible to deploy a model directly from a Jupyter notebook. Can you explain why this is not a preferable pattern, and what might you consider doing instead? Motivation: This is one of those questions that has less to do with “pure” data science and more about software engineering in general, and it’s also a question where the answer is less important than how the question is answered. In short, the reason this is not a preferable plan is because it...

This post will show you how to customize stubs used to generate various classes in your application. While a minor inconvenience, manually adjusting every generated class can be tedious, and Laravel provides a way for developers to publish and version stubs in an application if you want to suit generated classes to your specific taste. If you want to follow along, you can create a new Laravel project with the Laravel installer, using Sail, or any other way you prefer to create a new application: You might have noticed that the Laravel installer now supports Git and GitHub integration assuming you have the minimum git version required, you should have a new repository and a first commit. Versioning our demo project is an excellent way to visualize the stub changes we make along the way and see what kind of files Laravel publishes to the app. Publishing Stubs The first step in customizing stubs could be to add stubs you’d like to customize individually to the /stubs folder at the root of a Laravel project, or you can publish all of them with Artisan: As you can see, we have quite a few stubs published in the app folder! I’ll leave it up to you if you want to version all of them, but you could either keep a copy of them or only keep the specific stubs you want to customize. Custom Controller Stubs Laravel 8.36 introduced the idea of a --type flag when making a controller, allowing you to write custom stub files for generating a controller: After adding the custom stub class, you can generate a...
There are quite a lot of articles/videos on Laravel + Vue CRUD, but not enough is published on the newest Vue.js 3 version, using the new Composition API. So, with this step-by-step detailed article, let’s fill in that gap, building a simple Company management form. Notice: the link to the final repository is at the end of the article. Install Laravel and Laravel Breeze We start from the very beginning, by installing a fresh Laravel project, and a Laravel Breeze starter kit: By this point, we should have a default Laravel Breeze with Tailwind CSS design, and Login/Register functionality: Creating Model and API CRUD We will manage one table called Companies, with four text fields: name, email, address, website. So, we create the model, and automatically create migrations with -m: This is the DB structure: database/migrations/xxxxx_create_companies_table.php: In the app/Company.php model, we make all fields fillable: Next, we create a Controller, with a few flags to generate exactly what we need: Personally, I like to use API Resources to transform the data. Although in this project, we won’t make any transformations, I still have a habit of generating them: And, inside of app/Http/Resources/CompanyResource.php, there’s this default code: Next, for validation, we generate a FormRequest class: In this case, I will re-use the same validation rules for both store/update functions, so this is the content of app/Http/Requests/CompanyRequest.php: We use those API Resource and Form Request classes inside of our app/Http/Controllers/API/CompanyController.php, which has this code: And, we tie it all together to call that Controller from the routes/api.php: In this simple project, we won’t use any Middleware, the routes are public. So,...
